I am considering giving my children the CAT (California Achievement Test) this year. I don't know of anyone who has used this test, but most of the homeschool testing websites use this one. Does anyone have personal experience with it or any other achievement test? We don't follow the state curriculum. We may be learning about the Roman Empire while the state schools are teaching American history. My interest is in finding out how my children perform on the basic skills portion of the test.
